Abstract (en)
[origin: WO2019170182A1] The invention relates to a device and method for avoiding an interruption in the welding process during friction stir welding, in particular breakage of the friction pin, wherein the device has: g) at least three strip-like sensors (8), oriented at an angle of 120 degrees to one another, on the long sides of a wedge-shaped tool dome (7), wherein the tool dome (7) guides a welding pin (19) by means of a tool receiving cone (28) and a welding shoe (11), and the sensors (8) are configured to determined force, pressure and travel, h) a conical evaluation means in the lower region of the tool receiving cone (28), which serves to receive a sensor (22) for sensing the axial force, the torque and the bending moment on the welding pin (19), i) a piezoelectric vertical adjustment means for the welding pin (19), j) an arrangement of a laser measuring sensor (10) in the region of the welding shoe (11), the directivity of which passes over a round hole (27) in the passage region of the pin tip (12), wherein an airborne noise sensor (3) is arranged opposite the laser measuring sensor (10) and a welding shoe temperature sensor is provided, k) a sensor signal amplifier (23) having a rotor antenna for receiving, amplifying and passing on all sensed measured values, wherein these measured values are passed on to a machine controller by a static antenna (16), l) an inductive power supply system for supplying the measuring system from a moving secondary winding (24) and a stationary primary winding (25).
